1：Introduction Overview

Refractory castable with its good performance, good fluidity, plasticity and other characteristics are widely used in various industries, refractory castable variety, in the construction can be directly poured, is a more popular wear-resistant refractory material.

2：Stir

Mixing mechanical mixing and manual mixing, the current use of mortar mixer mix, in the construction, should be strictly in accordance with the standard, must be strictly measured.

Mixing: dry mix and then wet mix, first large bags and then small bags into the blender for mixing, the weight of mixing should be determined according to the amount of construction, the time is not less than three minutes, so that the refractory castable has fluidity, mixing precautions are as follows:

(1) The stirrers and tools used in the construction process need to be cleaned in advance, and must not be mixed with gravel, cement and other debris;

(2) Tap water must be used when mixing, and as little water as possible, so as to achieve good construction results;

(3) The amount of each stirring should not be too much, and the congealed block material can not be used again with water.

3: Pouring

Before construction, it is necessary to check whether the accessories are firm and remove some debris in the mold.

4: Maintenance

The curing temperature should be between 15-35 ° C, if it exceeds this temperature, corresponding measures should be taken to cool down, so as not to cause the performance of the product to decline; After the completion of the hardening of the castable, it can not be knocked and shaken within a day, and it can be released after 24-30 hours of hardening.

5：Bake

Baking is the last link in the use of castable, and the temperature is prohibited when pouring, otherwise it will cause certain accidents.
