Production Equipment

The spray drying spray booth is operated by means of upper air supply and lower air exhaust. When the painting process is carried out, the blower and the exhaust fan are simultaneously started (if the temperature of the operating environment needs to be raised in winter, the heating system is also started at the same time).
The outdoor fresh air is purified by the air inlet through the air inlet filter and enters the heating blower group; then the air flow is sent to the static pressure chamber at the top of the spray booth by the blower, and the filter cotton at the bottom of the static pressure chamber is subjected to the air flow. After pressing,
Blocking solid dust; after filtering, it enters into the spray booth at a uniform wind speed, forming a top-down breeze airflow around the workpiece and the operator, so that the remaining paint mist generated during painting will flow down with the airflow and will not diffuse to the surroundings.
To protect the operator’s labor safety. The average no-load wind speed in the room is O. 3~O. 5 m / s. Under the action of the ordered airflow, the paint-containing mist air passes through the light grille into the ventilating trench, and most of the paint mist bypasses the trench grille.

In the following baffles, due to the sudden refraction of the airflow, the paint mist particles settle on the folding plate with the inertia, and the remaining fine paint mist particles pass through the paint mist filter cotton under the baffle again with the air flow to carry out the remaining paint mist particles. filter,

The purified airflow is discharged to the outdoor sky through an explosion-proof exhaust fan. The paint mist purification efficiency is ≥95%.

A plastic working method that flows out of a specific die hole to obtain the desired cross-sectional shape and size, and is mainly used for the production of bars, tubes and profiles of stainless steel, nickel-based superalloys and refractory alloys.

Hot extrusion is the earliest extrusion technology used in several extrusion processes. It is a variety of extrusion molding of metal by means of the good plasticity of the material at hot forging temperature. At present, hot extrusion is mainly used to manufacture long sections, profiles, pipes, rods and various machine parts of ordinary equal sections.

Hot extrusion can not only form non-ferrous metals and their alloys with low plasticity, relatively low strength, low- and medium-carbon steels, but also high-carbon and high-alloy steels with high strength, such as special structure, stainless steel and high speed. Tool steel and heat resistant steel. Since the billet must be heated to the hot forging temperature for extrusion, it is often accompanied by more serious heating defects such as oxidation and decarburization, which affects the dimensional accuracy and surface roughness of the extruded part. In general, after the machine parts are hot extruded, machining such as cutting is used to improve the dimensional accuracy and surface quality of the parts.
