Production requirements of scraper
Apr 13, 2020

The blade scraper is a cooling and crystallization process, the molten material in the material plate and the cooling drum contact, in the surface of the drum to form a material film, through the material film and the heat transfer between the femoral wall, so that the material film cooling, crystallization, crystallization of the material film was scraped off by the scraper, into sheet products.

 

There are three feeding methods: feeding, feeding, feeding. According to the characteristics of chemical materials, there are single drum and double drum.

 

The material groove heat preservation has steam heat preservation, heat conduction oil circulation heat preservation, electric heat preservation.

 

The equipment is divided into open type and semi-closed type, fully closed type, vacuum type, nitrogen protection type.

 

Blade material, brass, phosphor bronze, nylon, bakelite, alloy steel saw blade.

 

Discharge system has single, double, etc.

 

Special requirements: regular shape and size of the material, to ensure the thickness and size uniformity of the material.

 

The cooling or (heating) system is split jacket type or spray type, according to the size of the slicer and the characteristics of the material to design, can improve the heat transfer efficiency and increase the drum strength, and improve the relative product output.

 

The cooling water adopts packing seal or rotary joint, which can reliably prevent water leakage, and the new process is applied to reduce the consumption of cooling water.

 

Both ends of the drum have heat insulation layer and side scraper, both ends of the drum do not knot, so there is no friction at both ends of the drum power consumption, to eliminate the problem of starting instability due to the end of the knot
