Method for measuring internal size of Hastelloy bowl

The invention belongs to the technical field of Hastelloy grindability tests, and particularly relates to a method for measuring the internal size of a Hastelloy bowl. Comprising the following steps: (1) preparation: preparing a mold filling solution and required tools and equipment; (2) mold filling and demolding: preparing a mold filling mixed solution, pouring the mold filling mixed solution into the Hastelloy bowl for mold fixing operation, obtaining an internal model of the Hastelloy bowl after the mold filling mixed solution is solidified, and taking out the internal model of the Hastelloy bowl from the Hastelloy bowl after mold fixing is completed; (3) measurement: using a vernier caliper and an angle measuring gauge to measure the horizontal track arc radius and the horizontal track center diameter of the Hastelloy bowl internal model to obtain Hastelloy bowl internal dimension data; and (4) wear degree judgment: before the Hastelloy bowl is used for the first time, and after the Hastelloy bowl is use
