Five Types of Ramming Materials Introduction

In industrial production, protecting and maintaining high-temperature thermal equipment is crucial. Various refractory materials, especially ramming materials, play a key role. Ramming materials of different materials have their own unique characteristics and application ranges and can meet the needs of different industrial furnaces. This article will introduce five different materials of ramming materials, and let us understand their characteristics and application fields.

Five types of ramming materials

وفقًا لأنواع الأفران العالية المختلفة ومتطلبات تصميم المواد المختلفة, carbon ramming materials are mainly used in the gaps between the blast furnace bottom carbon bricks the bottom sealing plate between the hearth carbon bricks and the cooling stave, and The leveling above the center line of the furnace bottom water-cooling tube and the filling of the cooling stave require that the carbon ramming material after ramming has a certain strength and density, filling every corner and small gaps to achieve impermeability. The requirements for leakage of molten iron and gas, and the thermal conductivity of the carbon ramming material must be consistent with the performance of the hot carbon bricks and cooling staves of the blast furnace, so as not to affect the life of the blast furnace and maintain normal production of the blast furnace.

في الوقت الحالي, a common problem encountered in the use of carbon ramming materials is that the thermal conductivity of general carbon ramming materials is low, وهو ما لا يفضي إلى التبريد السريع لجسم الفرن العالي, thereby affecting the service life. لذلك, the updated research and application of carbon ramming materials with high thermal coefficients have great market prospects. Whether adding admixtures to the carbon ramming material, changing the properties of the material through in-situ reactions at high temperatures, أو تغيير هيكل استخدام المواد المحلية من منظور التصميم, the carbon ramming material layer can reach the same level as the carbon ramming material when the working temperature rises. The thermal conductivity of the bricks and cooling staves matches to ensure normal heat conduction without damaging the overall construction structure, thereby achieving the requirement of improving the service life of the blast furnace.

كتلة صدم السيليكا

The main raw material of silica ramming material هو السيليكا. Silica is the general name for vein quartz, الكوارتزيت, والحجر الرملي الكوارتز. Mainly used in acid refractory bricks for the metallurgical industry. Pure silica can be made into quartz glass or refined single-crystal silicon. In the chemical industry, it is used to prepare silicon compounds and silicates, and can also be used as a filling in sulfuric acid towers. In the building materials industry, it is used in glass, السيراميك, Portland cement, إلخ.

كتلة صدم اكسيد الالمونيوم

مادة صدم اكسيد الالمونيوم is a bulk material made of corundum, كربيد السيليكون, الجرافيت, and electrically calcined anthracite as raw materials, مختلطة مع مجموعة متنوعة من إضافات مسحوق متناهية الصغر, and fused cement or composite resin as a binding agent. It is used to fill the gap between the furnace cooling equipment and the masonry or the filling material for the masonry leveling layer.

كتلة صدم المغنيسيوم

Magnesia ramming material هي مادة سائبة مصنوعة من المغنيسيا المنصهرة كمادة خام, mixed with a variety of ultra-fine powder additives, and fused cement or composite resin as a binding agent. It is used to fill the gap between the furnace cooling equipment and the masonry or the filling material for the masonry leveling layer.

Medium frequency furnace ramming mass

The medium-frequency induction furnace has an induction coil made of copper tubes wound around the outside of the furnace. يتم وضع الشحنة المعدنية في الفرن. عندما يمر التيار المتردد عبر ملف الحث, يتم إنشاء تدفق مغناطيسي متناوب في الملف. من خلال الشحنة المعدنية المغلقة, the furnace charge An induced current is generated within a certain depth on the surface, مما يتسبب في تسخين الشحنة وذوبانها. The furnace lining is made of refractory materials, والتي تتطلب مقاومة جيدة للتآكل, مقاومة التقشير, لا الشقوق, and a long service life. The material used in the intermediate frequency furnace is the ramming material of the intermediate frequency furnace, and its main performance indicators are.
