Resin sand production line of resin sand regeneration, green sand casting defects than other less production of resin sand reclamation equipment, scrap rate, high precision casting size, the surface is clean and clear outline, and so on. But resin sand reclamation equipment offer, if used improperly resin sand reclamation site equipment suppliers, there will be quality problems, and sometimes even lead to scrapped. 1. Stoma: There are two main 1) the evolution of gas, the gas vent invasive form of resin sand; 2) compounds, nitrogen-containing resin poured in nitrogen and hydrogen to liquid iron decompose, condense into gas separation, too late when the formation of pinholes . By ductile iron, to prevent the use of measures to meet the conditions of the molding sand, the lower the amount of resin strength; additional reinforcement core exhaust, ignition air entraining injection casting. Dust ①, pay attention to the fan when rapping or blowback precipitator ash rapping open when the motor and the motor can not start cleaning, or affect the discharge of dust effects. Time visualization dust content may be. ②, pulse dust collector attention must be manually cleaning the class. ③, joins situation every week to check the bag to prevent excessive dust bag off row. ④, when the dust of work prohibited to use welding equipment in the production line, or easily inhaled Mars burn bag. ⑤, air volume control valve timing checked regularly to prevent loosening after matching unreasonable amount of wind influence the effect of dust. ⑥, dust is likely to use the pipeline for many years at the bottom of the pipe affect the accumulation of dust dust effects, such as increased dust in the workshop to replace the bag and no significant improvement, it is recommended to clean the pipe.
