Embodiment Construction
[0004] The technical scheme that the present invention adopts is: use No. 8 (diameter is 4mm) heat-resistant steel wire to make square mesh bar, the shape of making is the same as the present hanger shape, puts into the mould, then well with stirring (the amount of water added is 5 -8%) steel fiber castables for pouring, after the castables are hardened for 24 hours, demould, then carry out moisture curing, the curing humidity is greater than 90%, the curing temperature is 10-30°C, and the total curing time is 3 days. Then bake for 40 hours with a 250W infrared lamp. The inner tube hanging piece produced by steel fiber castable has just been completed (specification, size are the same as the heat-resistant steel hanging piece produced at present).

Abstract
The invention discloses a manufacturing method of steel fiber casting material of inner-cylinder suspension piece for dried method rotary kiln preheater of new typed cement, which adopts thermal proof steel to prepare inner cylinder suspension piece.
Description
Technical field: [0001] The invention belongs to the equipment used in the preheater of cement new-type dry process rotary kiln. Background technique: [0002] At present, the known preheater inner tube hanging piece is produced with heat-resistant steel. Its production process is complicated, and the cost is too high, resulting in the high price of the inner cylinder hanging piece in the market. Invention content: [0003] In order to overcome the high production cost of the inner cylinder hangers used in the existing cement new dry-process rotary kiln preheater, the present invention uses a material instead of the original heat-resistant steel material, that is, steel fiber castables are used to produce the inner cylinder hangers of the preheater. Sheet, its service life is 1-1.5 years, high temperature resistance (≥1600 ℃), impact resistance, compressive strength ≥130Mpa, flexural strength ≥12Mpa, the main performance is the same as the heat-resistant steel hanging she...
