Problems solved by technology

Because the forming cylinder is under high-speed operation, the friction force is very large, and the metal material of the forming cylinder currently used cannot meet the high friction environment, resulting in excessive wear of the forming cylinder; on the other hand, the current forming cylinder The manufacturing process results in a high dust environment for the forming cylinder, causing rapid wear of the forming cylinder

Embodiment 1

[0028] The wear-resistant non-metallic forming cylinder used for biomass forming machine. The forming cylinder is composed of three parts: forming tube, shape-preserving tube and sleeve. The forming tube is made of alumina ceramics, and the alumina content is 90-98% , the iron oxide content does not exceed 0.1%; the shape-preserving tube is made of 30CrMo alloy steel; the sleeve is made of ZG310-570 cast steel.

[0029] During manufacturing, the forming tube is formed by isostatic pressing and sintered at a high temperature of 1700°C for 50 hours; the non-metallic forming sleeve is integrally cast with cast steel, and the surface finish of the inner wall of the forming sleeve is not less than 3.2 through boring machine processing during the casting process; The type tube is manufactured by the manufacturing process of inner hole carburizing: the workpiece is placed in the active carburizing medium, heated to 900 ° C, and kept for 20 hours, so that the activated carbon atoms dec...

Abstract

The invention relates to a manufacturing process and technology for a wear-resisting non-metal forming tube in a biomass forming machine. The forming tube consists of a forming pipe, a sleeve and a form maintaining pipe, wherein the forming pipe is matched with the sleeve in a binding manner, and the sleeve is in transition fit with the form maintaining pipe; and the forming pipe is made from a wear-resisting non-metal material. According to the invention, the service life of the forming tube is greatly prolonged, and the maintenance cost of the biomass forming machine can be lowered.

Description

technical field [0001] The invention relates to a wear-resistant non-metal forming cylinder for a biomass forming machine and a manufacturing process thereof. Background technique [0002] Bio-straw belongs to renewable energy and can be used as fuel to achieve C0 2 Zero emissions of greenhouse gases, but most of the straw is directly burned, causing great environmental pollution and energy waste. Vigorously developing biomass briquettes will make full use of biomass straw and convert it into renewable energy that can be transported. It is not only beneficial to environmental protection, but also can make full use of biomass resources. [0003] Because straw has the characteristics of small free volume density and low energy density, it can be compressed and molded by a biomass molding machine at a certain temperature (110-160°C) and pressure (10-30MPa). Biomass molding machines are divided into various forms. The hydraulic biomass molding machine relies on the hydraulic d...
