Embodiment 1

[0050] See attached Figure 1~8 As shown, the sugarcane squeezing roller repair process of the present invention is realized by the following scheme:

[0051] The process steps of the sugarcane squeezing roller repair process of the present invention are as follows:

[0052] 1) Pre-heat treatment: Put it in a heating furnace and heat it at a temperature of 100°C;

[0053] 2) Surface cleaning: Use a manual welding torch to clean the surface of the press roll obtained by the above step 1) preheating to remove the rust on the surface of the roll and the moisture and sludge that infiltrate the inner tissue of the roll;

[0054] 3) Turning removal: lathe turning to remove the fatigue layer of the roller surface layer;

[0055] 4) Measurement: Measure the worn squeeze roller to obtain the amount of wear and confirm the welding thickness;

[0056] 5) Welding repair: Welding repairs on the worn press rolls by using a welding machine on a lathe, leaving a machining allowance of 2-5mm for the rep...

Abstract

The invention relates to the technical field of machining of sugar factory machines, in particular to a sugarcane squeezing roller shaft restoration process for a sugar factory. The sugarcane squeezing roller shaft restoration process for the sugar factory includes the following process steps of pre-heating treatment, surface removing, turning removing, measuring, welding repairing, annealing treatment, ageing treatment, rough turning machining, finish turning machining, surface hardening pretreatment, journal hardening treatment, grinding and warehousing. The squeezing roller shaft restoration process has the characteristics that the process is simple, convenient and easy to implement, and low in restoration cost; a restored sugarcane squeezing roller shaft is stable in quality, high in strength and hardness, and good in durability; and the structure is reasonable, and the using adaptability is wide.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing in sugar factories, in particular to a process for repairing sugarcane squeezing rollers in sugar factories. Background technique [0002] Sugarcane, a tall solid perennial herb. The rhizome is thick and well developed. It is widely grown in southern tropical regions such as Taiwan, Fujian, Guangdong, Hainan, Guangxi, Sichuan and Yunnan. Sugarcane is a temperate and tropical crop. It is a raw material for the manufacture of sucrose, and ethanol can be extracted as an energy substitute. Sugarcane is rich in sugar and water. It also contains various vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism. Sugarcane also has the functions of clearing away heat and detoxification, promoting body fluids and quenching thirst, and relieving stomach and vomiting. The effects of nourishing yin and moisturizing dryness are widely l...
