Wear resistance testing device for phosphate wear-resistant brick

Abstract

The invention discloses a wear resistance testing device for a phosphate wear-resistant brick and relates to the technical field of refractory bricks. The device comprises a shell, an inner bottom surface of the shell is fixedly connected with a driving motor, one end of an output shaft of the driving motor penetrates through the shell and is fixedly connected with a friction wheel, the inner bottom surface of the shell is fixedly connected with a controller, a top surface of the shell is fixedly connected with a switch and a display screen, an output end of the switch is electrically connected with an input end of the controller through an electric wire, and an output end of the controller is electrically connected with an input end of the driving motor through an electric wire. Accordingto the wear resistance testing device, the descending speed of a refractory brick after friction is amplified through a transmission structure of a rotary gear and a connecting rope, the improvementof the detection precision is facilitated, the rotating speed of the rotary gear is measured by a speed measuring sensor, the rotating speed of the rotary gear is converted into the descending speed of the refractory brick by the controller, compared with the prior art, the wear resistance of the refractory brick can be visually observed and tested, and reading errors are avoided.

Description

technical field [0001] The invention relates to the technical field of refractory bricks, in particular to a wear-resistant testing device for phosphate wear-resistant bricks. Background technique [0002] Phosphate-bonded high-alumina brick is a kind of unburned brick, which is made by semi-dry machine pressing and heat treatment. The raw material is dense special-grade bauxite clinker, phosphoric acid with a concentration of 42.5%-50% is used as a binder, and the heat treatment temperature is 400-600°C. The use of phosphoric acid combined with high alumina bricks greatly increases the wear resistance of refractory bricks, the stability of hot and cold, and increases the strength of refractory bricks; The volume shrinks during use; adding fused corundum and mullite in the form of a matrix can improve the softening temperature under load and corrosion resistance. [0003] Phosphate high alumina bricks have the following characteristics: 1. High temperature resistance; 2. H...

Problems solved by technology

The existing phosphate wear-resistant bricks lack wear-resistant testing links and corresponding testing devices, and it is impossible to objectively understand the wear-resistant performance of phosphate wear-resistant bricks, and manual readings of wear-resistant tests are prone to errors. Therefore, a wear-resistant wear-resistant brick is developed. Testing device is a technical problem that those skilled in the art need to solve
