What do you need to know when buying آجر نسوز?

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. محل کوره با استفاده از آجرهای نسوز

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. از عملکرد عادی و عمر کلی کوره اطمینان حاصل کنید

به عنوان روکش کوره ، عملکرد عادی و عمر کلی کوره باید تضمین شود. آجرهای نسوز مختلف مورد استفاده در قسمتهای مختلف کوره را بطور منطقی پیکربندی کنید. هنگام تعیین قسمتهای مختلف کوره و مواد هر لایه از یک قسمت ، از واکنشهای شیمیایی و آسیب ذوب بین آجرهای نسوز مختلف اجتناب کنید و اطمینان حاصل کنید که تلفات هر قسمت متعادل است ، یا اقدامات منطقی را برای متعادل کردن تلفات انجام دهید. و از عمر کلی کوره اطمینان حاصل شود.

3. ویژگی های آجرهای نسوز

چه زمانی 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. تولید کنندگان آجر نسوز

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.
