Description Of Our Product
Due to the high mold requirements of the refractory industry, high precision, high wear resistance, and long product life are the basic needs. Especially the wear resistance, the surface of the template gets worn easily because the template is subject to the forming pressure exerted by the brick press, which creates a great friction force between the brick and the template. Generally, if the wear reaches 0.3-0.4mm, it is not allowed to continue to use. Therefore, the template is required to have good wear resistance.
The refractory mold industry now faces several bottlenecks that are impacting its development: limited availability of skilled labor; high cost of raw materials; environmental regulation and limited innovation.
We are now offering innovation of carbide liners for refractory brick mold.
With a slightly higher cost of tungsten carbide, this composite material can bring unexpected rewards not only in the longer service life, but also higher precision, hardness, and wear resistance. All these properties will conversely save customers costs in reduced downtime for repairing or replacing the molds.
These liners are brazed on the template of the steel-made mold, and we use advanced techniques of vacuum brazing in this process. This brazing method can generate less inner stress and effectively remove the oil and oxide film from the surface of the welded parts. Therefore, customers' cars rest assured on our carbide liners for refractory brick mold to make a difference.
The evolution of the way brazed Carbide sheet to steel backing plate
| Products of all generations |  |  |  |
| Material | Carbide | Carbide | Tungsten cement carbide and steel parts |
| Technology | Braze the entire carbide plate to the mold. | Brazing entire steel parts with carbide sheets | Braze the carbide sheet to the smaller steel backing plate and drill the threaded holes |
| Advantages | 1. Low cost 2. Low technical requirements | 1. Extend product life compared to ordinary materials. 2. The number of pressings can reach more than 9400 times | 1. High hardness, high strength, and high wear resistance. 2. Longer product life 3. Resistance to high temperature and high-impact situations. 4. The integrity of the mold is higher. 5. The number of pressings can reach more than 15,000 times |
| Disadvantages |
| 1. Higher unit price 2. Lifespan still cannot meet production needs 3. Cracks may occur during use | 1. High unit cost. 2. Hard to reprocess, the service quality of suppliers is very important. |
The evolution of the materials we selected
1. For The first generation, we use modified cast iron, A3 steel, low carbon steel, and 45# steel. Improve surface hardness and wear resistance through heat treatment, reaching hardness HRC60-64. Then made the pressing mold. The advantages of this generation are low costs and fast delivery time, but product life is short.
2. The main materials of the second generation are tool steel and high-carbon steel. Compared to ordinary materials, product life is extended, but not enough. Higher costs lead to lower Cost-effectiveness, still cannot meet market requirements.
3. In the third generation, we started to use Tungsten cement carbide and steel parts. This composite material can bring unexpected rewards not only in the longer service life, but also higher precision, hardness, and wear resistance. As improved by many of our customers, our products successfully save their costs in reduced downtime for repairing or replacing the molds. In particular, customers who have used our carbide refractory brick molds have reported that the probability of cracks and chips that often occur in refractory brick molds has been greatly reduced.
