Firebrick is a kind of high temperature building material and structural material that is widely used in building kiln and all sorts of thermal engineering equipment, use utility is extensive, always in working temperature is in the high temperature equipment of 200℃ above can use firebrick, about the price of firebrick also is uneven on the market, the noble and cheap price of firebrick basically sees product quality.Therefore, when buying refractory bricks, we must take into account the demand of both price and quality.
There are three tips to buy refractory brick to share with you:
First, look at the proportion of impurities in firebrick.Generally speaking, there will be impurities in the process of sintering refractory bricks in strict accordance with the proportion of ingredients, without perfect products, do not affect product quality.But some manufacturers often can not press production with material scale, make sintered refractory brick does not have hard structure, make sintered brick quality does not pass a standard thereby, finally shoddy with high price to cheat consumer.So when you buy firebrick, you can look through its surface.The surface of the firebrick with high impurity content in general will be very rough, and the overall color of the firebrick with good quality is even, the surface is smooth and flat, which is we can distinguish intuitively from the surface.
Second, is the firebrick sintering experiment, this method is the most effective.Usually when we buy firebricks, we will take samples for testing in advance.Especially before we decide to buy, we must let the manufacturer to carry out high temperature test, in order to check whether the sintering index of the refractory brick is the same as the standard index.As long as the deviation of the experimental results is not large, the quality of the brick body is still up to standard, which is also a good method.
Third, use the weighing method.Firebricks have their own size and bulk density, which can be used to calculate the weight of individual blocks.Because of the different aluminum content and production process, the single weight of firebrick is different.After receiving the goods, the purchaser can randomly select several pieces for weighing, measure and record the weight, and then bake the sample in a high temperature environment for a period of time to test the weight and see if there is any change in the weight.No change proves that the supplier of the product is a reliable manufacturer. If the weight of the product changes, then you should be on your guard.That's because any company that sells its products at a higher price now "sprinkles" the surface of a lower grade of firebrick to meet customers' weight requirements.
