Abstract

The invention belongs to the technical field of blade material production, and particularly relates to a production line and a production method for blade material production of a single specification. The production line and the production method for the blade material production of the single specification aims at the defect that existing blade material production technology must produce blade materials of multiple specifications, resulting in the production efficiency reduction and raw material waste. According to the technical scheme, the production line comprises a smashing device, an airflow classifier, a pulping pool, a purified pool and an overflow classifier, wherein the smashing device, the airflow classifier, the pulping pool, the purified pool and the overflow classifier are connected in sequence. The production line further comprises a grinding device, wherein a material circulating pipe I is further arranged between the smashing device and the discharge part of the lowerportion of the airflow classifier; and the overflow classifier comprises a first overflow classifier and a second overflow classifier, wherein a feed inlet of the first overflow classifier communicates with the purified pool, a discharge port of the lower portion of the first overflow classifier communicates with a feed inlet of the second overflow classifier, a discharge port of the lower portionof the second overflow classifier communicates with the grinding device, and the discharge port of the grinding device communicates with the feed inlet of the first overflow classifier through a material circulating pipe II. The production line and the production method for the blade material production of the single specification apply to the production of cutting blade materials.

Description

technical field [0001] The invention belongs to the technical field of blade production, and in particular relates to a production line and a production method for producing blades of a single specification. Background technique [0002] Crystal silicon wafer cutting edge means that the cutting edge material of the cutting machine is crystal silicon wafer. It is mainly used in the cutting of solar crystal silicon wafers and semiconductor wafers, and is one of the three major consumables for wire cutting of silicon wafers. During the wire cutting process, the sand mixed with the cutting fluid (usually polyethylene glycol) and the cutting edge is sprayed onto the wire net composed of thin steel wires, and the cutting edge in the mortar is combined with the cutting edge through the high-speed movement of the thin steel wires. The surface of the silicon rod or silicon ingot tightly pressed on the wire is ground at high speed. Since the cutting edge particles have very sharp edg...
