What do you need to know when buying batu bata tahan api?

What do you need to know when buying refractory bricks? What kind of furnace lining is used for refractory bricks? Can refractory bricks achieve practical application effects? How to purchase refractory bricks to achieve good results? Combining the actual situation, expounds the refractory brick procurement Issues that should be paid attention to.

1. Lokasi kiln menggunakan batu bata tahan api

According to the structure of the furnace, the working characteristics and operating conditions of each part of the furnace, refractory bricks are selected to achieve targeted selection. For example, the lining and bottom of various smelting furnaces below the slag line (such as furnaces and reverberatory furnaces) are mainly chemically attacked by slag and metal melt, followed by thermal stress caused by temperature mutations. The masonry generally chooses magnesia and magnesia-chrome refractory bricks with good slag resistance. The above slag line can choose magnesia alumina brick, magnesia chrome brick or high alumina refractory brick.

2. Pastikan operasi normal dan umur tungku secara keseluruhan

Sebagai lapisan kiln, operasi normal dan masa pakai kiln secara keseluruhan harus dijamin. Cukup konfigurasikan berbagai batu bata tahan api yang digunakan di berbagai bagian tungku. Saat menentukan berbagai bagian tungku dan bahan dari setiap lapisan bagian yang sama, hindari reaksi kimia dan kerusakan leleh antara batu bata tahan api yang berbeda, dan pastikan bahwa kehilangan setiap bagian seimbang, atau ambil langkah-langkah proses yang wajar untuk menyeimbangkan kehilangan dan memastikan umur tungku secara keseluruhan.

3. Karakteristik batu bata tahan api

Ketika buying refractory bricks, you should master the basic knowledge of refractory bricks, such as the composition of refractory bricks, the physical properties and working performance of refractory bricks, and whether it can achieve the expected effect as a furnace lining, so as to better exert the excellent characteristics of refractory bricks. For example, silica bricks for coke ovens have a high softening temperature under load and can resist acid slag erosion, but their thermal shock resistance is poor and can only be used for coke oven partition walls. Their soft load characteristics can be used in long-term high temperature environments.

2. Produsen bata tahan api

As a purchaser of refractory bricks, you only need to determine the index, size, performance and other information of refractory bricks to purchase common refractory bricks, and consult the refractory brick manufacturers whether they can make them, whether they can meet the specified requirements, and whether the processed refractory bricks can meet the requirements Characteristics and other information, this is the most basic integrity of refractory brick manufacturers.
