Intelligent hot and wet tensile strength touch screen tester QR-ZSL-A

It is mainly used to determine the hot wet tensile strength and room temperature wet tensile strength of molding sand, as well as to identify the quality of raw materials such as bentonite.

It is one of the main testing methods for judging the anti sand inclusion performance of molding sand.
Adopting contemporary microcomputers, intelligent control of linear stepper motor loading system, intelligent temperature control automatic lifting system, and intelligent measurement system. Adopting a color LCD touch screen Chinese operating system, high-precision force sensors, etc. Fully automated testing, data processing, real-time display of curves, and storage of the entire process. Functions such as querying and displaying curves, and printing data. It is a high-precision measuring instrument used in modern scientific research, teaching, and production.

1, Working principle
The hot wet tensile strength tester is designed to simulate the mechanism of moisture migration in sand molds when heated. The hot wet tensile strength is the tensile strength measured at the high water layer formed by heating the sample. Principle: During testing, place the prepared sample along with the sample cylinder onto the main sample guide rail. After automatic timed heating at the bottom of the sample (320 ℃, about 20-30 seconds), a certain thickness of dry sand layer (about 4mm) and moisture condensation zone are formed on the heated surface of the sample. Then automatically load and display the force process curve, measure its tensile strength, display the measurement results, store and print the report.
