To ensure that the quality of plug bricks meets the high-standard industrial demand, we need to start from many aspects such as raw material selection, production technology, quality control and product design improvement. The following are specific measures:

I. Control of raw materials

Select high-quality raw materials: the raw materials of plug bricks usually include pyrophyllite, graphite, high-purity carbon powder, etc. The binder is 811 resin with solid content greater than 70%, and St powder is added as antioxidant. These high-quality raw materials can ensure that the plug brick has good high temperature resistance, corrosion resistance and oxidation resistance.

Strict inspection of raw material quality: Strictly analyze the chemical composition and physical properties of the purchased raw materials to ensure that they meet the production standards.

II. Optimization of production process

Improve the molding process: adopt a special mold to optimize the overall molding process of the plug brick. For example, the joint is placed in the mold in advance, and then the refractory material is added for pressing, so as to avoid the problems such as non-vertical or deformation of the pin and the plug, thus improving the overall strength and reliability of the product.

Control the production process: In the production process, the key parameters such as molding pressure, impregnation time and dry distillation temperature are strictly controlled to ensure that the density, strength and porosity of the plug brick are optimal.

III. Quality control system

Establish a perfect quality inspection process: strict quality inspection should be carried out in every link from raw materials storage to finished products delivery. The inspection items include chemical composition analysis, physical performance test (such as compressive strength, thermal shock resistance) and appearance inspection (dimensional accuracy, surface defects, etc.).

Refined management: record and trace each batch of products in detail, and once problems are found, they can be quickly located and taken measures to solve them.

IV. Product design improvement

Optimization of structural design: The new integrated plug brick cancels the design of filling refractory, reduces the erosion of the end of the spherical cap, and effectively eliminates quality accidents such as "turning around".

Customized service: provide customized plug brick products according to the use needs of different customers, including the adjustment of size, shape and material to meet the use requirements under specific working conditions.

V. Application and feedback

Monitoring of actual use effect: during the customer's use, continuously track the performance of plug bricks, collect feedback information, find potential problems in time and make improvements.

After-sales service support: provide professional technical support and after-sales service to help customers solve problems encountered in the use process and ensure the stability and reliability of plug bricks in actual production.

Through the above measures, the quality of plug bricks can be effectively ensured to meet the high-standard industrial demand, thus ensuring the smooth progress of steel production process and the stability of product quality.
