Benefits of technology

In this process called cogging roll-forming (CCF), which involves melting or quenching large diameter materials in an oven at high temperatures without causing any problems such as cracks that could occur during traditional methods used for making very small material sizes. Additionally, it allows for flexibility with regards to processing different types of sheet metal while maintaining its quality level.

Problems solved by technology

This patented technical problem addressed in this patents relates to controlling the overall length (total) of rolling up thin gauges made of high strength materials such as stainless steels or chrome alloys during manufacturing processes like hot forming without overloading any equipment beyond what was designed specifically for these types of material.

[0022] Billet B is a billet of conventional production specifications, which can be used for the normal billet size of the heating furnace; billet A is used for rolling 6mm thick limit specification steel plate, and its length specification is 2500mm, which cannot be used for the normal billet size of the heating furnace. Put the blank B as the back blank, place the blank A as the back blank on the top of the blank B, use the blank B to carry the blank A, and send it into the heating furnace for heating.

Abstract

The invention discloses a carrying blank rolling method for producing a steel plate of the 6mm-thickness limit specification through a medium-thickness plate. A blank B of the conventional productionspecification is adopted for carrying a steel plate blank A of the limit specification, the blank B and the steel plate blank A are fed in a heating furnace at the same time to be heated, and the blank B and the steel plate blank A are separated through a separator after being discharged out of the furnace to be rolled respectively. Compared with the prior art, the method has the beneficial effects that in the carrying blank rolling method for producing the steel plate of the 6mm-thickness limit specification through the medium-thickness plate, the method that the conventional blank carries the blank of the limit length specification to implement carrying blank heating and rolling is completed through discharge blank separation is adopted, the problem that blank specifications are limitedand cannot be suitable for the normal blank mounting size of the heating furnace can be solved, meanwhile, the rolling danger existing in rolling of steel plates of the limit thin specification and damage to equipment are avoided, and existing thick plate production equipment is utilized for producing the steel plates of the limit thin specification.
