Cast steel brake plate is an important part of automobile brake system.
The cast steel material gives the brake plate high strength and wear resistance, and can withstand the huge pressure and friction generated during the braking process.
Its main role is to provide installation support for the brake shoe and transfer the brake reaction force to the vehicle chassis.
In terms of design and manufacture, the shape and structure of the cast steel brake plate have been carefully designed to ensure a precise fit with the other components of the brake system and to achieve an effective braking effect.
High-quality cast steel brake baseplate usually has good casting quality, smooth surface, uniform internal organization, no porosity, slag inclusion and other defects, so as to ensure the stability and reliability of its performance.
In the market, the price of cast steel brake floor will vary depending on the brand, model, quality and other factors. The price of cast steel brake bottom plate of some common models is usually between tens of yuan and hundreds of yuan.
If the cast steel brake plate is worn, deformed or damaged, it will affect the braking performance, resulting in brake failure, brake deviation and other safety hazards, which need to be replaced in time.

The replacement cycle of automobile brake floor is not fixed, it depends on many factors.
In general, if the vehicle is used normally, the driving conditions are good, and the maintenance is proper, the brake floor may not need to be replaced when the vehicle travels more than 100,000 kilometers or even longer.
However, if the vehicle is often driven in harsh road conditions, such as dusty, wet, high-corrosion environment, or the driving habit is more aggressive, frequent sudden braking, the brake plate may be subjected to greater wear and impact, thereby shortening its service life.
In addition, if the brake system fails, such as excessive wear of the brake disc, brake pump failure, etc., it may cause additional damage to the brake bottom plate, in which case it also needs to be replaced in advance.
Regular inspection of the working state of the brake system, including the condition of the brake floor, is an important measure to ensure driving safety. If the brake bottom plate is found to have obvious wear, cracks, deformation and other problems during the inspection, it should be replaced in time to ensure the normal operation of the brake system and driving safety.

The production process of a cast steel brake plate usually includes the following steps:
Mold design and manufacturing: According to the design requirements of the brake floor, the precise casting mold is made. The quality and accuracy of the mold have an important impact on the size and shape of the final product.
Smelting cast steel materials: The selected cast steel raw materials (such as carbon steel, alloy steel, etc.) are put into the furnace for melting, so that it reaches the appropriate temperature and composition uniformity.
Casting: The molten steel is poured into the mold, and the casting speed and temperature should be controlled to avoid porosity, slag inclusion and other defects.
Cooling solidification: After the casting is completed, the casting is cooled and solidified naturally in the mold to form a preliminary blank of the brake bottom plate.
Demoulding and cleaning: After the casting is cooled and solidified, it is removed from the mold, and impurities such as molding sand and oxide are cleaned off the surface.
Preliminary processing: preliminary mechanical processing of the blank, such as milling, drilling, etc., to remove the excess part, so that the shape is roughly in line with the requirements.
Heat treatment: Through quenching, tempering and other heat treatment processes, improve the structure and performance of cast steel, improve its strength, hardness and toughness.
Finishing: More precise machining, such as grinding, honing, etc., to achieve specified dimensional accuracy, surface roughness and form and position tolerances.
Quality inspection: Non-destructive testing (such as ultrasonic testing, magnetic particle testing, etc.) and dimensional testing are used to conduct a comprehensive quality inspection of the brake bottom plate to ensure that it has no internal defects and meets the design standards.
Surface treatment: According to the need, the surface treatment of the brake bottom plate, such as spray painting, galvanized, etc., to improve its corrosion resistance and appearance quality.
The above is a common production process of cast steel brake bottom plate, which may be adjusted and optimized according to specific product requirements and production conditions in actual production.
