Six-power support roller profile curve

Abstract

The invention relates to a six-power support roller profile curve, and belongs to the technical field of steel strip production equipment in the metallurgical industry. According to the technical scheme, the equation of the support roller profile curve is f(x)=p1*x^6+p2*x^5+p3*x^4+p4*x^3+p5*x^2+p6*x+p7, wherein x is the support roller body length coordinate, p1, p2, p3, p4, p5 and p6 are coefficients of the sixth power, the fifth power, the fourth power, the third power, the second power and the first power of the equation correspondingly, p7 is the constant term of the equation, and E is thescientific counting method; and the support roller profile curve is ground by a numerically-controlled grinding machine. The six-power support roller profile curve has the beneficial effects that thefinished strip steel plate type can be improved, and the sentence reduction rate of the plate type is reduced from 4.63% to 0.06%. The six-power support roller profile curve is a one-time grinding curve, chamfers on the two sides of a support roller do not need to be separately ground, and the grinding efficiency of the support roller is improved.

Description

technical field [0001] The invention relates to a hexagonal support roll profile curve, which belongs to the technical field of strip steel production equipment in the metallurgical industry. Background technique [0002] Products with good shape and quality are used in the manufacture of automobiles and home appliances, and the market demand is large. At present, hot rolling technology at home and abroad is developing towards shape, thickness accuracy, precise control of temperature and performance, and surface quality control. The shape control of strip products has always been the main problem that manufacturers at home and abroad are trying to solve. Poor shape has a great impact on production stability, cost, operating rate and product quality. Improving the shape quality of thin gauge and variety steel has significant economic benefits for stable production, improving operating rate, reducing abnormal consumption of rolls, and improving product quality. It can also pro...

Problems solved by technology

[0003] The 1700 production line is a common production line for strip steel production in the metallurgical industry at present, including the rolling process and the skin-passing process. Due to the poor roll shape of the 1700 finishing mill and the support roll of the skin-pass mill, the finished strip generally has double-sided wave defects. The thinner the thickness, The higher the strength, the more serious the double-sided wave defect will be, which will have a greater impact on the subsequent production process and equipment, and some products will eventually be reduced or quality objection due to poor board shape.
