Mould assemblies are key equipment for continuous casting. We produce round,square,rectangular and beam blank mould assemblies of different sizes with material of stainless steel and carbon steel. We have vertical and curved types in structure, The precision of mould assemblies are guaranteed as the forged stainless water jackets are produced by extrusion while assembled water jackets are machined by high precisionn CNC machines.

Mould Material

TP2 is a kind of material is selected by most of the steel plants.It shows excellent heat-proof and anti-fatigue property under high temperature and it has good processing property.

CuAg0.1 with 0.08%-0.12% silver during copper ingots melting will increase the recrystallization temperature of copper by 100C, which will increase the heat stress and anti-abrasive property of copper mould tube interior surface, showing better heat resistant property than TP2.

Cu-Cr-Zr is a kind of copper alloys which can be normalized by time.It has excellent mechanical property under both room temperature and hight temperature. It has hight heat conductivity, melting point, anti-fatigue and anti heat stress properties. Their outstanding features make it different from the previous copper alloys. It combines all good properties together. But compared with other copper alloys, Cu-Cr-Zr is difficult to be formed with higher products costs.

Mould & Plate Coatings

Copper has lower hardness which leads to lower anti-abrasive property. Therefore, the area at the lower part of the moulds, where the stress increases drastically due to shells, will be more severely worn. To increase the life time of copper moulds, LMM provides uniform mould interior surface plating with suitable hardness. Most of the copper mould tubes for small size billet casting are not used in any casting system where there are rigid casting stream support, therefore they are very sensitive to be worn. We use hard chrome plating to increase the life of mould tubes. The plating thickness recommended by LMM will be controlled in the best range. As for the coating of copper mould plates, based on our years of experience, we are able to provide Cr coating, Ni-Cr coating, Ni-Fe coating and Ni-Cr coating to meet the demand of various customers both at home and abroad.

Research & Development

Our company has 50 technicians and 15 of them have  senior professional titles. We have strong ability to develop products of various materials and sizes (Square, Rectangular, Round, Nonstandard and Beam Blanks, with range from the smallest of 50×50mm to the largest of Dia.1500mm round tubes, 500×500mm Square tubes, 120×650 rectangular tubes). Strong R&D abilities can meet the customers demand to the maximum extent.  The perfect combination of experience and theories constantly improves the quality of our products. We are dedicated to shaping steel!

Quality Assurance

The target of our work is to improve our technological capacities to be in the interest of the customers. For the purpose, we have been dedicated to new products development. We established R&D department for new alloys, optimized copper taper and better anti-abrasive coating. Our physical and chemical laboratories are equipped with advanced analysis and inspection devices which provides strong guarantee for the quality of our products.
