Quartz crucible preparation process, quartz crucible and crystal pulling method

The invention discloses a quartz crucible preparation process, a quartz crucible and a crystal pulling method, relates to the field of quartz crucible preparation, and aims to solve the problem of liquid level shaking in the crystal pulling process. According to the technical scheme, the quartz crucible preparation process is characterized by comprising the steps that S1, quartz sand is poured into a melting rotary mold, and straight-wall bubble layer quartz sand is formed through a forming rod; s2, scraping off the quartz sand on the straight wall part by using a forming rod to enable the quartz sand to fall into the bottom until a bubble layer on the outer surface of the whole crucible is formed; s3, transparent layer stage: forming the straight wall of the coarse-particle natural quartz sand to be below the liquid level line by using a forming machine until the coarse-particle natural quartz sand is formed; s4, using a forming machine to form quartz sand for the remaining part which is not formed by the fo
