Abstract
The invention discloses a fish-scaling-resistant enamel glaze for hot-rolled steel plates, which comprises the following components in parts by mass: 40 parts of high-temperature glaze, 30 parts of intermediate-temperature glaze, 30 parts of low-temperature glaze, 18 parts of 1000-mesh calcined quartz, 7 parts of clay, 0.3 part of borax, 0.2 part of sodium nitrite, 0.3 part of magnesium carbonate and 1 part of special adhesive agent. Through collocating with porcelain glazes with high, intermediate and low different softening points, the fish-scaling-resistant enamel glaze prepared by using the method disclosed by the invention facilitates the purging of most of gas generated in the process of enameling hot-rolled steel plates, so that fine uniform bubble structures are formed on a porcelain glaze layer, therefore, an effect of accommodating gas gradually discharged from the steel plates is achieved, and finally, a purpose that an enamel glaze product for hot-rolled plates does not have the phenomena of bubbling and porcelain shedding is achieved; and the adherence intensity of the enamel glaze is not reduced.
Description
Technical field
The present invention relates to a kind of fish-scaling-resistant enamel glaze for hot-rolled steel plates.
Background technology
Many weeks: steel, in Hot rolling, extends ratio large, but surface is easily oxidized, and the ferric oxide of generation and a small amount of slag or impurity are likely pressed in steel plate, cause surface irregularity; Hot-rolled temperature, generally at about 1000 DEG C, often rolled once, needed to carry out pickling with certain density hydrochloric acid, and like this, the hydrogen that hot-rolled steel sheet dissolves than cold-rolled steel sheet is more.So, hot-rolled steel sheet burns till at enamel produce more gas with meeting in use procedure than general enamel cold-rolled steel sheet, is easy at surperficial enamel enamel defects such as making enamel coating generation bubble pin hole, particularly squama quick-fried, thus, hot-rolled sheet is generally not suitable at surperficial enamel.But, due to the chemical industry equipment rush of demand such as hot rolling Plate Steel counterenamel large-sized biogas generation tank, aqua storage tank in recent years, the vitreous enamel for hot-rolled steel sheet is had very large demand.
Enamel on hot-rolled sheet is except will having the effect of stronger adherence with steel plate; enamel firing also will be made in the bubble structure of the enamel layer formation fine uniform of hot-rolled steel sheet; play the effect holding expellant gas gradually from steel plate, enamel coating obviously can not be bubbled and protect enamel coating in life-time service process, there will not be the quick-fried and de-porcelain of squama.
Summary of the invention
The technical problem to be solved in the present invention is, by high, normal, basic different softening point enamel of arranging in pairs or groups, the most of air scavenge will produced during enamel firing is conducive to when hot-rolled steel sheet enamel firing, enamel layer forms the bubble structure of fine uniform, play and to hold from steel plate expellant gas gradually and finally reach the object of non-foaming, the de-porcelain of hot-rolled sheet enamelware, do not reduce again the adherence strength of enamel, develop a kind of fish-scaling-resistant enamel glaze for hot-rolled steel plates, to achieve the above object.
Object of the present invention realizes by the following method: high adherence strength, low firing temperature, can produce the fish-scaling-resistant enamel glaze for hot-rolled steel plates of fine uniform bubble structure, and composition proposal is in mass ratio: high melting glaze 40, medium temperature glaze 30, low temperature glaze 30,1000 order calcining quartz 18, clay 7, borax 0.3, Sodium Nitrite 0.2, magnesiumcarbonate 0.3, special adhesive agent 1.

The mass ratio of described special adhesive agent is composed as follows: NiO 7-8, CoO 0.2-0.3, Li
2o2-3.
Production process is as follows:
(1), respectively high melting glaze, medium temperature glaze, low temperature glaze chemical constitution are taken raw material by above-mentioned mass ratio formula, after mixing, wire drawing 1-2 joint/rice is melted in the High Temperature Furnaces Heating Apparatus of about 1300 DEG C, discharging cooling cold water swashs broken or rolls sheet, respectively obtained high melting glaze, medium temperature glaze, low temperature glaze.
(2), special adhesive agent chemical constitution is taken raw material by above-mentioned mass ratio formula fully mix, 150 DEG C of insulations 20 minutes, then be warming up to 580 DEG C of insulations 3 hours, form nickel cobalt lithium crystalline oxides, naturally cooling, is crushed to 200 order all-pass.
(3), the high melting glaze after oven dry, medium temperature glaze are crushed to particle diameter to 50-200 micron, low temperature glaze is crushed to particle diameter to 50-100 micron, and 1000 order calcining quartzs, clay, borax, Sodium Nitrite, magnesiumcarbonate, special adhesive agent are crushed to particle diameter 10-50 micron.
(4), by above-mentioned fish-scaling-resistant enamel glaze for hot-rolled steel plates formula each powder is mixed, pack with waterproof bag.
The invention has the beneficial effects as follows:
Low temperature glaze mainly produces good adherence effect with steel plate: in low temperature glaze, use Li
2o and Na
2o, K
2o, produces " mixed alkali effect ", to reduce the firing temperature of low temperature glaze.Lithium Oxide 98min is a kind of very strong fusing assistant, when especially using together with potassium felspar sand or albite.For the Lithium Oxide 98min of equal in quality, the molecule number that sodium oxide and potassium oxide comprise, yes, and Lithium Oxide 98min is maximum, and therefore its fluxing action is the strongest.Lithium ion radius is little, is easily clipped in vitreous state enamel structure, makes glaze paint fine and close, reduces pin hole, smooth surface, and dissolves quartzy ability also than the enamel containing potassium, sodium by force containing lithium enamel, can reduce the linear expansivity of enamel.Its mobility also can be made to increase, and surface tension reduces, and softening temperature and melt temperature reduce, and burn till and shorten with the fusion time; Reasonably combined cobalt, nickel oxide is also introduced, to ensure that enamel has good adhesion property in low temperature glaze.Make low temperature glaze just can produce good sticking power with steel plate reaction under lower temperature conditions.
Medium temperature glaze mainly forms uniform bubble structure: in medium temperature glaze, introduce the materials such as lazurite, Fluorspar Powder and Sodium Silicofluoride, to increase the bubble structure of enamel.Lazurite contains Strontium Sulphate, and the strontium oxide generated after decomposing is excellent solubility promoter, can help to reduce enamel firing temperature; Fluorspar Powder, Sodium Silicofluoride decompose in enamel can produce F
2, SiF
4gas, can form the bubble structure of fine uniform.
High melting glaze mainly improves corrosion resistance nature: introduce zirconium silicate to improve water tolerance and the alkali resistance of enamel at high melting glaze.Because the purposes of hot-rolled sheet enamelware mainly makes water tank, methane-generating pit, therefore need good water tolerance and alkali resistance.The main component of zirconium silicate is zirconium dioxide.In enamel, zirconium dioxide is the optimal components improving enamel water tolerance and alkali resistance.Enamel containing zirconium dioxide is called zironium glaze.One of feature of zironium glaze has good surface strength, and enamelware can be made durable in use.
For strengthening the adherence of enamel and steel plate, in mill addition, use special adhesive agent, to ensure that enamelware has excellent adherence strength.
By the fish-scaling-resistant enamel glaze for hot-rolled steel plates that the inventive method is obtained, be a kind of acid-and base-resisting corrosion, the vitreous enamel of hot-rolled steel sheet can be used for, the defect such as occur bubble after preventing hot-rolled sheet enamel and squama is quick-fried.
