The most critical area in continuous casting is where the liquid steel turns into solid form. This is where the mould and related technologies come into existence to achieve successful and high-quality castings. LMM GROUP with decades of experience in moulds and surrounding technologies, will direct you to the best solutions for success.

Productivity, operation and billet-quality are influenced to a large extend by the efficiency of the copper-moulds. High speeds of > 4 m/min require intensive and uniform heat-flux which can be achieved with innovative mould design.

Extra-long service-life is achieved with the special LMM GROUP multilayer Ni-Co-Cr coating, which features high micro hardness and optimum binding strength with the copper base.

LMM GROUPtubes are designed for maximum heat transfer rate from the meniscus down to the bottom of the tube.  The taper-geometry depends on the steel-grades and casting conditions and is designed with the aim of minimizing the gap between the solidifying shell and the copper tube.

Extra-long service-life is achieved with the CerMold plating. This multilayer Ni-Co-Cr structure features high micro hardness and optimum binding strength with the copper base.

LMM Brand Copper Mould for continuous casting machine in steelmaking is available for :

billet caster, bloom caster, beam blank caster, slab/thin slab caster.

1. We supply high quality and durable copper mould tube with most competitive price and prompt delivery.

2. Our Copper Mould Tube meet ISO9001 standards, high precision and meet hardness requirement, perfect taper and coated layer.

3. We have complete facilities to process every copper mould tube,galvanize plating, hardness testing to provide accurate Chromium plating to the Mould Tubes to achieve high performance in heat resistance.

4. We manufacture thousands pieces of copper mould tube every month and supply to several biggest Steel Group in China which proved that our product is most trusted and satisfy by our customers.

Our Product:

  • Our main products: Square, Rectangular, Round and Beam Blank copper mould tubes. With dedicated to research of new technologies, we continuously develop various sizes, materials and special shapes, large and super large size mould tubes.

  • We also developed various types of high efficiency copper mould tube for continuous casting machine.

  • Our products range also features mould assembly and other metallurgical spare parts. Apart from copper mould tubes, we also produce various types of copper mould plates and assembled beam blank moulds.

Up-to-date electro-plating technologies:

  • We have complete electro-plating 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.

Various sizes and types of copper mould tubes and plates have been supplied to world’s top steel manufacturer Arcelormittal, TATA Steel, EZZ steel etc. We do OEM for Concast and Danieli for a long time

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, which can produce Dia.1500mm round tubes and 3800x1000x70mm copper plates.

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. lt 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.

Production Process

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, CCM 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 CCM 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.
