Description
Technical field
The present invention relates to a kind of method of continuous manufacturing steel band, the side plate that described method is used at least two casting rollers and perhaps arranged on side direction, wherein, being in operation to cast at these constitutes the casting pond between roller and the side plate, the steel melt of liquid state can be fed into the casting roller from this casting pond.
Background technology
When steel melt low-carbon (LC), the calmness of manganese/silicon (Mn/Si) part is made steel band, in using the twin-roll type continuous casting method known according to prior art, many crackles and blemish often appear in the steel band of being produced, thereby have obviously reduced the quality of the steel band of being produced.
Known by WO03024644 and US2005145304, for fear of or reduce crackle and blemish at least and select the composition of steel melt in this wise, promptly, the non-metallic inclusion of the liquid state that in steel melt, forms, it is liquid that this field trash keeps when box hat solidifies, and realize the hot-fluid of homogeneous by formation liquid film on casting roller surface, and then realize the cooling effect of homogeneous.In industrial fusion work, in esse manganese oxide/silica (MnO/SiO in the steel melt of Mn/Si part calmness
2) ratio because operation is former thereby often often be lower than the ratio that theory calculates.The melt temperature of the non-metallic inclusion in the steel melt of Mn/Si part calmness is to the change of steel composition and to forming the MnO/SiO that changes in himself forming of being associated with steel
2The change reaction of ratio is very responsive.Therefore, during the metallurgical rule that in following prior art, provides, be used to make liquid non-metallic inclusion, what then lack in industrial fusion work is: each treated ladle all has following composition, and described composition guarantees the existence of liquid non-metallic inclusion in casting process.Therefore may still crackle and blemish can appear.
The invention task
Task of the present invention is, avoids the known disadvantage of prior art, and a kind of method is provided, and is used to make the steel band that does not farthest have crackle and blemish, and described steel band has by homogeneous surface low-carbon (LC), that the calm steel melt of Mn/Si part is made.In the method, the franchise of melt temperature of non-metallic inclusion of forming the deviation of ideal value with respect to steel should be enough to guarantee all to have liquid non-metallic inclusion in each treated ladle in industrial fusion work in casting process.
Detailed description of the invention
The ground according to the present invention, solve task of the present invention by the following method, in the method, normally in service, Mn content and steel melt Si content and that have definite sulfur content with definite ratio, the roll-force of adopt determining (roll separating force, processed under condition RSF).
Therefore, this method relates to a kind of method, be used to make the steel band that band is casting, low-carbon (LC), Mn/Si is partly calm, wherein, export steel melt the melt pool between the casting roller that moves together with steel band at least two and be cooled, and on these casting rollers, be frozen into steel band at least in part, it is characterized in that, steel melt have 20 and 300ppm between sulfur content, and Mn/Si ratio 〉=3.5, and under the situation of operate as normal, roll-force 2 and 50kN/m between.
Be that the steel band of Zhi Zaoing does not farthest have crackle and blemish and has the homogeneous surface by this way unexpectedly.
Can be understood as for the steel band of low-carbon (LC) is following steel band, and in described steel band, carbon content is lower than 0.1 weight %.
The composition according to the present invention of steel melt has guaranteed the low melting glass of non-metallic inclusion.Low melting glass causes, and at box hat solidificating period on these casting rollers, non-metallic inclusion exists with liquid state in casting process.By widening the franchise of compositing range (in this compositing range, liquid non-metallic inclusion is present in the multiphase system) raising with respect to the melt temperature of the non-metallic inclusion of the deviation of steel composition ideal value.The described compositing range of widening has guaranteed that even when accurately not satisfying ideal value in the industrial fusion work for the steel of determining is formed, steel melt still has the composition of guaranteeing that in casting process liquid non-metallic inclusion exists.
In the process of preparation steel, non-metallic inclusion oxide type or sulfur compound appears in the steel melt.In the steel melt of Mn/Si part calmness, the main component of non-metallic inclusion is MnO and SiO
2
By according to the present invention ground with sulfur content adjust to be in 20 and 300ppm between value and the Mn/Si ratio is adjusted into 〉=3.5 value can realize that non-metallic inclusion is manganese oxide-silica-manganese sulfide (MnO-SiO by main component mainly
2-MnS) multiphase system is formed.If the share of the MnS in this multiphase system is lower than 37 weight %MnS, then the melt temperature of this multiphase system is lower than by main component MnO and SiO
2The melt temperature of the multiphase system of forming.This three-phase system MnO-SiO
2-MnS has the ternary eutectic thing under about 1130 ℃ situation.
Three-phase system MnO-SiO shown in Figure 1
2The model of-MnS, this liquid phase zone is at MnO-SiO
2The eutectic point of binary boundary system is to touch MnO-SiO in eutectic point under 1251 ℃ the situation
2The binary boundary system, and this liquid phase zone is widened along with the increase of MnS content when transitting to three-phase system.When temperature was lower, this liquid phase zone moved apart boundary system, and only from beginning greater than certain MnS minimum content, had this liquid phase zone.
Under steel melt composition situation according to the present invention, the exemplary operation point is in and is approximately 15 weight %MnS, and described exemplary operation point has the low melting glass of non-metallic inclusion and enough melt temperature franchises with respect to the fluctuation of MnS content in industrial fusion work simultaneously.
By the solidify situation of help simulation in thin strap continuous casting equipment of etch experiment (wherein, cast ground to inert gas, time of contact and overheated the adjustment corresponding to band, and the sulfur content of steel melt 150 and 500ppm between), draw average MnS content in the liquid non-metallic inclusion between 7 and 40 weight %.The higher sulfur content of the steel melt that the Mn/Si part is calm causes the MnS content of non-metallic inclusion also higher.
Fig. 2 illustrate low-carbon (LC), Mn/Si part steel melt (0.05 weight %C calm, Mn/Si ratio 〉=3.5; 0.7 weight %Mn; 0.2 sulfur content weight %Si), the influence that tearing tendency (this tearing tendency is by the cracking frequency or represent by the width between the melting zone of steel melt) is caused, and the influence that the melt temperature (liquidus temperature) of the composition and the non-metallic inclusion of non-metallic inclusion is caused.Measurement data among Fig. 2 is obtained by above-mentioned etch experiment.
When the following sulfur content that is lower than melt (described sulfur content cause non-metallic inclusion with about 1130 ℃ the time ternary eutectic thing corresponding M nS-content) time, along with the rising of sulfur content, the melt temperature of non-metallic inclusion descends.When the following sulfur content that is higher than melt (described sulfur content cause non-metallic inclusion with about 1130 ℃ the time ternary eutectic thing corresponding M nS-content) time, the melt temperature of non-metallic inclusion and the cracking frequency suddenly raise.Width between melting zone increases the sulfur content until about 300ppm, and basic then maintenance is constant.
The opposition performance of the hot tearing tendency of the rising of non-metallic inclusion shown in Figure 2 and the melt temperature of decline.Therefore, can derive the sulfur content that ground is recommended according to the present invention, under the situation of this sulfur content, realize the enough low melt temperature of non-metallic inclusion and realize tolerable hot tearing tendency simultaneously according to Fig. 2.The existence of sulphur in the steel alloy, when reducing its solid-state temperature, the widening of solid-liquid two-phase region that also causes steel alloy, promptly, cause widening between the melting zone of steel alloy, thus, the temperature range that the heat cracking occurs between liquid infiltration temperature LIT (Liquid ImpenetrationTemperature) and zero plasticity temperature ZDT (zero ductility temperature) is widened.
When the sulfur content in steel melt reaches 300ppm, increase to about 45 ℃ to this width substantial linear of two-phase region.From this sulfur content, owing to when sulfur content increases, in process of setting, separate out MnS, constant thereby the width in two-phase zone keeps basically.These MnS precipitates are deposited on the casting roller surface with solid forms, and hinder the hot-fluid of homogeneous or the cooling effect of homogeneous thus, thereby help the formation of blemish and crackle.The sulfur content of the rising of steel melt causes the amount of MnS precipitate to increase, and then causes the increase of blemish and crackle.Therefore, maximum sulfur is limited at 300ppm according to the present invention.Sulfur content at steel melt is lower than under the situation of 20ppm, with respect to by main component MnO and SiO
2The multiphase system of forming, the decline degree of the melt temperature of liquid non-metallic inclusion is big inadequately, thereby is not enough to guarantee the existence of liquid non-metallic inclusion when the box hat solidificating period is on the casting roller in casting process.In addition, when sulfur content is lower than 20ppm, the width that wherein liquid non-metallic inclusion is present in the compositing range in the multiphase system is big inadequately, thereby is not enough in industrial fusion work to guarantee enough franchises of the deviation of the ideal value formed with respect to steel.
Sulfur content is preferably 50ppm at least, especially is preferably 70ppm at least.The upper limit of sulfur content is preferably 250ppm, especially is preferably 200ppm.By desulfurization or by adding sulphur or sulphur compound controllably, make the sulfur content of steel melt reach the level of hope.
Mn/Si ratio in steel melt is lower than under 3.5 the situation, can not form by main component MnO-SiO
2The following multiphase system that-MnS forms in such multiphase system, is MnO and SiO with respect to main component
2Multiphase system, the melt temperature of liquid non-metallic inclusion enough is brought down below the value of the melt temperature of steel reinforced concrete compound greatly.So the ground according to the present invention, the ratio of Mn/Si must be greater than or equal to 3.5.
Roll-force is based on the power that width of steel band is demarcated, and the casting roller is with this power mutual extrusion in casting process.Roll-force has influence on the crackle of band casted steel belt and the existence of blemish.Roll-force is high more, and then the temperature inhomogeneity of locating to occur at " contact point " of box hat is just big more.This temperature inhomogeneity causes the inhomogenous cooling of steel band, thereby can cause face crack.Additionally form stress in the band casted steel belt owing to higher roll-force, this stress may cause the mechanical property of crackle and deterioration equally.
The use of very low roll-force has been avoided these problems and additional advantage is provided, that is, the mechanical load that Casting Equipment is born is less.Yet select low roll-force to bring negative effect to the stability of casting process, because have following danger under the low roll-force situation: the metal-back that solidifies on the casting roller is because inhomogeneity, when solidifying, be laminated deficiently, and steel band is influenced by its deadweight and ftractures; And box hat partly or be bonded on the whole length casting roller on, thereby cause box hat to split.In method according to prior art, under normal operation the size of casting roller separating force 5 and 250kN/m between.
The ground according to the present invention, roll-force is less than 50kN/m.Because reducing in the generation of box hat solidificating period inhomogeneity owing to the liquid non-metallic inclusion of assurance appearance makes according to composition of the present invention of steel melt is minimum, the danger for casting process stability can not appear so can adopt low roll-force like this.
The cracking frequency increases along with the increase of roll-force.Adopt to surpass under the situation of 50kN/m roll-force, can not guarantee to make steel band homogeneous, farthest do not have a surface of flawless and blemish.
The ground according to the present invention, the following 2kN/m that is limited to of roll-force.Be lower than the enough stability that this value can not guarantee casting process.Roll-force preferably is at least 5kN/m.The upper limit of roll-force is preferably 30kN/m.The normal operation that the setting of roll-force and Casting Equipment are stable is relevant, and when starting with equipment or the conditional independence when interim abnormal load occurring and influencing.
