Description

TECHNICAL FIELD

[0001] The utility model belongs to the water gap casting construction technical field, concretely relates to casting water gap heat treatment sintering automatic temperature control device. BACKGROUND

[0002] The casting water gap heat treatment sintering device is an equipment for high-temperature sintering treatment of the casting water gap, and through heat treatment sintering, the refractory material of the water gap can obtain good organizational structure and performance, such as high strength, high temperature resistance, corrosion resistance, etc., to meet the use requirements in the casting process.

[0003] The casting water gap is specifically put into the hearth by the casting water gap blank body after forming and drying treatment, and the heating system is started to gradually increase the hearth temperature to the predetermined sintering temperature. In the heating process, the temperature control system accurately controls the heating speed and temperature uniformity to ensure that the water gap blank body undergoes physical and chemical changes under suitable temperature conditions. If a specific atmosphere environment is required, the atmosphere control system will introduce the corresponding gas into the hearth according to the set requirements. When the sintering temperature is reached, it is maintained for a period of time to allow the blank to fully sinter and form a dense organizational structure to improve its performance. After sintering is completed, heating is stopped, and the water gap is slowly cooled to room temperature with the hearth, and then the finished product is taken out through the unloading device.

[0004] Specifically, as a key component in the casting process, the performance of the casting water gap directly determines the stability of the casting process and the quality of the castings. In the production process of the water gap, the heat treatment sintering link is undoubtedly the core element affecting its performance, however, the traditional heat treatment sintering method has many drawbacks. In terms of temperature control, it relies on relatively simple temperature control equipment, lacks high-precision temperature sensors and advanced closed-loop control systems, resulting in a large deviation between the actual temperature and the preset value, and the rate and length of temperature rise, holding and cooling cannot be strictly controlled. Due to uneven heat distribution in the furnace, the sintering temperature experienced by the water gap at different positions is different, resulting in unstable sintering effect. In actual production, this not only leads to large dispersion of key performance indicators such as hardness and density of the water gap, and obvious fluctuations in product quality, but also significantly increases the rate of defective products, causing waste of materials and energy, indirectly increasing production costs, and negatively affecting the economic benefits and market competitiveness of casting enterprises.
