Equipment

continuous casting equipment

As the old saying goes, one must sharpen his tool before going to make a perfect work, our company spends heavily on the manufacturing equipment of copper mould tubes and plates. Now we have 9 sets of large, medium and small hydraulic press, 30 sets of CNC machine centers, 2 sets special CNC processing machines, We have complete electroplating facilities, first class electro-plating equipment and up-to-date electro-plating technologies. We have two electro-plating workshops for mould tube plating and mould plates plating separately and each of them covers an area of 1800 square meters. There are 32 tanks for Cr plating of mould tubes and 7 tanks for plating of mould plates. The maximum siza of round tubes that can be plated is up to Dia.1500mm and the widest mould plates can be plated is up to 3800mm. We have advanced watertreatment system. We adhere strictly to the environmental policy of zero emission which makes our company a green and environment-preserving enterprise.

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 is adding 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 heatresistant property than TP2.

Cu-Cr-Zr is a kind of copper allys 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.

Coating

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 severelyworn. 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 NiCo-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 50x50mm to the largest of Dia.1500mm round tubes, 500x500mm 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!

We not only provide products, we also provide handicrafts, the mirror finished tubes surface is like a mirror.
