Abstract
The utility model discloses a through furnace steel plate capable of improving an effect of a through furnace, and belongs to the technical field of steel rolling heat treatment equipment. The through furnace steel plate is used for cleaning scale on the surface of a base roller of a roller-bottom-type hear treatment furnace. The technical scheme of the through furnace steel plate is that a through furnace steel plate body is an ordinary steel plate, four groups of grooves are formed in the lower surface of the through furnace steel plate and are arranged along the vertical axis sequence of the through furnace steel plate, each group of the grooves comprise two straight grooves, the back ends of the two straight grooves are located on the edges of two sides of the through furnace steel plate, the other ends of the two straight grooves extend to a middle axis of the through furnace steel plate, the two straight grooves are symmetrical about the middle axis of the through furnace steel plate, the two straight grooves have inclined angles with the same direction of the edges on the two sides of the through furnace steel plate, and the inclining angles of the straight grooves on the two sides of the four groups of the grooves are the same. When the through furnace steel plate passes through the furnace base rollers, the effect for cleaning the scale on the surface of the roller is improved greatly, roller marks on the lower surface of the steel plate are effectively controlled, the lower surface quality of the steel plate is improved obviously, and at the same time, the coping quantity of a normalizing steel plate is reduced.
Description
Technical field
The utility model relates to the logical stove steel plate that a kind of Steel Mill is used for the cleaning of roller hearth heat-treated furnace furnace bottom roll scale on surface, belongs to steel rolling equipment for Heating Processing technical field.
Background technology
Normalizing is normalizing treatment, but modern normalizing furnace is equipped with necessary cooling apparatus.Can carry out normalizing, tempering, quenching, the thermal treatment such as modified to steel plate.The visual plant of and thick steel plates high-quality for the plate of moderate thickness plant produced.Normalizing furnace is for the heat treated equipment of steel plate, and normalizing furnace is divided into two kinds of roller bottom type and stepped start-stop systems by type of drive, has flame heating and radiator tube to heat two kinds by heating means.Normalizing furnace is arranged on Heavy Plate Production line rear portion usually, and steel plate is carried out continuous thermal treatment.
At the bottom of open firing formula roller, stove furnace bottom roll surface cord can cause the steel plate following table to produce roll marks, reduces plate quality, and this is a difficult problem of generally acknowledging in the industry.Steel Mill's normalizing furnace generally uses the steel plate cycle to lead to stove in order to solve normalized steel plate following table roll marks problem, and logical stove plate used is common plain plate, and logical stove effect can not be satisfactory, is necessary to improve.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of logical stove steel plate that can improve logical stove effect, and this logical stove steel plate can improve logical stove effect, improves the surface quality of heat-treated steel plate.
The technical scheme that solves the problems of the technologies described above is:
A kind of logical stove steel plate that can improve logical stove effect, its body is common logical stove steel plate, lower surface at logical stove steel plate is provided with four groups of grooves, four groups of grooves are arranged sequentially along the longitudinal axis of logical stove steel plate, every group of groove is comprised of two straight grooves, the rear end of two straight grooves lays respectively at the both sides of the edge of logical stove steel plate, the other end arrives the medial axis of logical stove steel plate, two straight grooves are symmetrical with the axis of logical stove steel plate, and with logical stove steel plate both sides of the edge, the angle of inclination of equidirectional is arranged, the angle of inclination of the straight groove of four groups of groove both sides is identical.
The above-mentioned logical stove steel plate that can improve logical stove effect, the straight groove of described four groups of groove both sides and the angle of inclination 40-60 degree of logical stove steel plate both sides of the edge, directly the degree of depth of groove is 8-12mm.
The above-mentioned logical stove steel plate that can improve logical stove effect, the front end of a straight groove of every group of groove is crossed the central axis of logical stove steel plate, is positioned at the front end top of another straight groove, and the length of the straight groove of two adjacent groups groove alternately changes.
The beneficial effects of the utility model are:
After adopting this logical stove steel plate with many group grooves; logical stove steel plate is through furnace bottom roll the time; polish respectively furnace bottom roll surface of four groups of grooves; the more common logical stove steel plate of the cleaning effect of roll surface iron scale is improved a lot, and the logical stove effect of normalizing furnace has had obvious improvement, and steel plate following table roll marks has obtained effective control; the lower surface of steel plate quality has obtained obvious improvement; also reduce simultaneously the reconditioning quality of normalized steel plate, extended the logical stove cycle, improved furnace output.The statistic data demonstration, after using novel logical stove steel plate, normalizing furnace on average class produces 30 tons of raisings, ten thousand yuan/year of year cost reduction 85-100.The utility model is simple in structure, making is easy, logical stove is respond well, has significant economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: logical stove steel plate 1, groove 2.
Embodiment
Show in figure, body of the present utility model is common logical stove steel plate 1, is provided with 2, four groups of grooves 2 of four groups of grooves at the lower surface that leads to stove steel plate 1 arranged sequentially along the longitudinal axis of logical stove steel plate 1.
An embodiment of the present utility model is that the normalizing furnace bottom-roller diameter is 380mm; the distance in roller 2.25 weeks of rotation, 2.50 weeks, 2.75 weeks is respectively 2684.7mm, 2983mm, 3281.3mm, at logical stove steel plate 1 lower surface, four groups of grooves 2 is set according to such spacing.The furnace bottom roll surface can evenly be divided into A, B, C, four faces of D, first group of groove 2 of logical stove steel plate 1 contacts with roller at the A face, second group of groove 2 contacts with roller at the B face, successively the 3rd group of groove 2 at C face, the 4th group of groove 2 at the D face, logical like this stove steel plate 1 four groups of grooves 2 through furnace bottom roll time the polish respectively furnace bottom roll A, B, C, four faces of D improve a lot to the more common logical stove steel plate of the cleaning effect of roll surface iron scale.
Show in figure, every group of groove 2 is comprised of two straight grooves, the rear end of two straight grooves lays respectively at the both sides of the edge of logical stove steel plate 1, the other end arrives the medial axis of logical stove steel plate 1, two straight grooves are symmetrical with the axis of logical stove steel plate 1, and with logical stove steel plate 1 both sides of the edge, the angle of inclination of equidirectional is arranged, the angle of inclination of the straight groove of four groups of groove 2 both sides is identical.
