To ensure the quality of Shi Ying Shuikou brick, strict control should be carried out in production, testing and use. The following are specific measures:

I. Production links

(1) Selection of raw materials

Select high-purity silicon dioxide raw materials to ensure its purity is not less than 99.2%, so as to ensure the basic performance of Shi Ying Shuikou brick.

Strictly screen raw materials to remove impurities and harmful components.

(2) Optimization of production process

Shi Ying submerged nozzle brick with ceramic castable structure is made by advanced centrifugal casting method, which can ensure its stability in the casting process.

Optimize production parameters and process flow, such as controlling firing temperature and time, to ensure the stability of product quality.

II. Detection link

(1) Chemical composition detection

The chemical composition of Shi Ying Shuikou brick was accurately analyzed to ensure that the silicon dioxide content met the standard.

(2) Physical performance testing

Measure the bulk density, apparent porosity, cold compressive strength and bending strength to ensure that they meet the specified standards.

(3) NDT

X-ray flaw detection: X-ray penetration ability is used to detect internal defects, such as cracks and inclusions, which has high sensitivity and is suitable for on-site inspection.

Ultrasonic flaw detection: internal defects are detected by high-frequency sound waves, which is suitable for detecting cracks and inclusions.

(4) Visual inspection

Check the size deviation, deformation, cracks, corner defects, melting holes and abnormal color.

III. Use link

(1) baking and preheating

According to the characteristics of Shi Ying Shuikou brick, the proper baking process is formulated to avoid the damage of the brick body caused by the rapid temperature change.

(2) Installation and maintenance

Ensure that the installation position of Shi Ying Shuikou brick is accurate, so as to avoid failure during use due to improper installation.

Check regularly during use to find and deal with problems in time.

IV. Quality management system

Establish a perfect quality control system to monitor the whole process from raw material procurement to product delivery.

Strengthen the quality monitoring in the production process, and carry out sampling inspection on each batch of products.

Strictly deal with unqualified products and prohibit them from leaving the factory.

Through the above measures, the quality of Shi Ying Shuikou brick can be effectively ensured, and its performance and service life in practical application can be improved.
