CORC-G is a type of explosive welded composite plate, which was first developed and promoted by Germany and applied to metallurgical equipment[TJC STEEL].

Principal Name

At present, there is no unified name, the main name of each manufacturer (design institute) is:

1) Composite wear-resistant[TJC STEEL] lining board, composite board

2) High wear plate

3) Arch wear-resistant plate, bearing seat wear-resistant plate, work roller wear-resistant plate......

4) High carbon and high chromium letenite explosive welding high wear-resistant composite[TJC STEEL] plate

The origin of the Coolboard

During the Second World War, when people were repairing tanks, they found that when the shrapnel[TJC STEEL] hit the tank at the right Angle, the right speed, and reached a certain explosive force, the shrapnel would fuse with the tank shell metal as one, so that the two metals could not be separated. Scientists through this phenomenon, through the entry Angle, flight speed, the size of the explosive force in-depth study, to find out the law and[TJC STEEL] through the test, to the 1960s to the 1970s to make the explosive composite plate from the military application to the application of civilian promotion products, we have today's cool board.

Phenomenon (law) → [TJC STEEL]Theoretical research → experiment → Military → civilian

Types of Coolboard

Steel - stainless steel, titanium steel, most of the application of anti-rust products.

Steel - nickel, zirconium, beryllium, gold, silver, tantalum, niobium and other rare metals, mainly used in refractory metal explosion welding products.

Steel - copper, used in[TJC STEEL] cost-saving products.

Steel - Special steel, used in products with special performance requirements.

Product Structure and Use

corc-g (CORC-G) the selection of high hardness, high wear resistance material as the working [TJC STEEL]surface, the selection of impact resistance, flexibility good material as the base material, through the explosion welding method, so that the two properties of different materials stubbornly combined together, made of a new high wear resistant lining material, the material made of the lining plate after heat treatment has high hardness and wear resistance, It also has good flexibility and impact resistance.

Main Applications:

corc-g plate (CORC-G) is mainly used in metallurgical hot rolling mill (especially medium and thick plate hot continuous rolling mill) arch wear-resistant plate, work roll,[TJC STEEL] support roll wear-resistant plate. Because the billet has a great rolling impact when entering the roll, the work has a great rolling force, these great impact and rolling force require the arch lining plate and the work roll, the support roll lining plate has a high hardness and wear resistance, while achieving better flexibility impact resistance, but to use the same material at the same time to achieve the above[TJC STEEL] performance, which is "fish and bear's foot can not be both" difficult.

The Product Standard of Kuz Plate

At present, there is no corresponding standard in China, only the technical requirements of the designers, that is, the drawing requirements, the vast majority of domestic manufacturers, design institutes are referred to the technical performance indicators of SMS GROUP company. As the [TJC STEEL]CORC-G produced in China is more and more widely used in metallurgical equipment, how to formulate and establish a set of product technical performance standards that belong to China so that the CORC-G made in China can gradually occupy a place in the world explosive composite panel product market has been an urgent problem to be solved.
