Mould Accessaries
- The mould housing is a very important part of the continuous casting machine. It is a bottomless steel billet mould assembly with forced water cooling. Its performance is critical to the quality of the continues billet caster.
- Production capacity and billet quality play a very important role, so it is called
- the “heart” of continuous casting equipment.
- Function of crystallizer
- The mould is the core part of the continuous caster. Important functions of mould crystallizer are as follows:
- 1. At the highest possible pulling speed, it is ensured that sufficient shell thickness is formed when leaving the mold to resist the static pressure of molten steel without pulling
- Leakage;
- 1. The shell thickness around the mold can grow uniformly and stably;
- 2.The interaction between molten steel slag phase billet shell copper wall in the mold determines the surface quality of the billet
- Sexual impact. The first function determines the productivity of the continuous casting machine; 2)、
- 3. It determines the surface quality of casting slab.
- 4. Performance of crystallizer
- a. It has good thermal conductivity and can quickly form a primary shell with sufficient thickness;
- b. It has good structural rigidity and structural processability, which is convenient for processing and manufacturing, easy for disassembly and adjustment;
- c. Good wear resistance and high thermal fatigue resistance;
- d. It is light in weight so as to have a small inertial force during vibration.

Taper of Copper Mould Tubes
COBAX as the builder of metallurgical plant, our professional knowledge enables us to develop and design the most suitable taper for any steel. Under the same conditions, the acceptance of copper tubes with different taper and other mass production practices have proved the professional authority of our development technology. We can recommend the best internal geometry according to abax technology, or make it according to your copper tube drawing. All possible taper are available: single taper, multi taper, parabolic, convex, diamond taper.
Coating of Copper Mould Tubes
COBAX electroplating plant has the world's leading electroplating technology, which can strictly control the coating thickness, and the coating thickness of copper tube corner and side wall are strictly monitored within the tolerance range. The coating in the mould copper tube plays a decisive role in the life of the copper tube. Cobax high-quality European process hard chromium coating and composite coating ensure that the steel throughput of each copper pipe is doubled. The Ni Co multilayer structure has high hardness and the best copper based bonding strength. The coating can also be designed and customized according to customers' requirements.
Inspection of Copper Mould Tubes
COBAX has its own intellectual property precise testing instrument, measuring the internal geometry of each mould copper pipe, and generating relevant inspection report. In addition, the laboratory also supervises and controls every process from copper billet to final mould copper tube.
Product Application
COBAX has a first-class European design team, which can design and customize the mould copper tubes of various billet according to the customer requirements
