There are several types of refractory each with its own unique properties.<\/p><\/blockquote>\n

Thus, choose the right refractory installation<\/strong> by knowing the type of application.<\/strong><\/p>\n

What is Refractory?<\/h2>\n

In general, refractory is the process of using <\/span>refractory equipment<\/strong> for heat-resisting containers<\/span><\/span>. Also, it supports combustion processes or molten solids <\/span>undergoing heat treatment.<\/strong><\/p>\n

Basically, thermal insulation <\/strong>and conduction<\/strong> are the two main features of refractory products. Hence, <\/span>refractory materials<\/strong> control and conduct <\/span>heat through the walls to the charge.<\/span><\/p>\n

Types of Refractory<\/h2>\n

Commonly<\/span><\/span>, the refractory industry uses refractory supplies. Such as <\/span>high alumina cement, fire clay bricks, refractory tiles, <\/strong>and insulation bricks.<\/strong> Furthermore, there are many types of refractory materials for a variety of applications.<\/span><\/p>\n

Hence, the right type of refractory<\/strong> can control the changing conditions of furnaces, boilers, chimneys, and kilns<\/span>. Here we will list the different types of refractories available in Malaysia.<\/p>\n

Refractory Types & Its Application in Malaysia<\/h2>\n

1. Brick Refractory<\/h3>\n

Generally, refractory brick contains ceramic, aluminum oxides, and silica. This helps provide excellent heat resistance.<\/strong> Also, there are even some types of refractory bricks that can withstand over 2,100\u00b0C.<\/p>\n

Apart from that, fire clay bricks<\/strong> are anti-flammable and insulate very well. This firebrick reduces energy loss <\/span>significantly<\/span><\/span> and avoids the possibility of a fire.<\/span><\/p>\n

Brick refractory applications:<\/strong><\/p>\n

Refractory lining and insulation bricks. Such as for chimneys, kilns, furnaces, ovens, and other high-temperature structures.<\/p>\n

\n

2. Plastic Refractory<\/h3>\n

Basically, plastic refractories use refractory materials with high plasticity for longer durability. It is a paste-like material made of a binder, plasticizer, and water.<\/p>\n

\n
Moreover, refractory plastics have high plasticity before they harden. Yet it is <\/span>considerably<\/span><\/span> stronger once hardened. Also, it has an ideal sintering property, volume stability, and heat resistance. <\/span><\/div>\n<\/div>\n

\n
Besides, you can also bake plastic refractory into sheets\/blocks following the application of refractories.<\/span><\/div>\n
<\/div>\n<\/div>\n

Plastic refractory application:<\/strong><\/p>\n

Incinerators, soaking furnace, boilers, steel oven, furnace burner, etc.<\/p>\n

3. Ramming Refractory<\/h3>\n

Basically<\/span><\/span>, a strong ramming process forms <\/span>refractory ramming mass<\/strong> <\/span>into a bulk structure. This includes a blend of refractory <\/span>aggregate<\/span><\/span>, a binder, and an additive.<\/span><\/p>\n

In addition<\/span><\/span>, it comprises fire clay, a high alumina base, corundum, silica, carborundum, or magnesia<\/span><\/span>.<\/span> So, the ramming mass is notably resistant to chemicals, erosion, abrasion, and shock.<\/p>\n

Ramming refractory application:<\/strong><\/p>\n

Electric furnace, tapping trough, open-hearth furnace, induction furnace, etc.<\/p>\n

4. Patching Refractory<\/h3>\n

Typically<\/span><\/span>, it can repair the <\/span>refractory lining<\/strong> of industrial furnaces. Moreover, patching refractory is <\/span>easy to manage <\/strong>and<\/span> increases a structure’s service life<\/strong><\/span>.<\/strong><\/p>\n

However, the refractory patching materials<\/strong> depend on the applications. For example, refractory grouting material, refractory pressing material, refractory spraying coating, and refractory pouring material.<\/p>\n

Patching refractory application:\u00a0<\/strong><\/p>\n

Blast furnace, converter, iron trough, reheating furnace, electric furnace, etc.<\/p>\n

\n

5. Coating Refractory<\/h3>\n

Also called foundry coating<\/strong>, refractory coatings can resist the high heat of the molten metal. This protective coating is the barrier between a hot molten metal and the core surface.<\/span><\/p>\n

Hence, once the paint is applied, it evaporates leaving a refractory layer on the sand surface. Then, the layer will act as a wall to reduce molten metal penetration. <\/strong>Which will prevent sand erosion thus improving the refractory casting surface.<\/p>\n

Coating refractory application:\u00a0<\/strong><\/p>\n

Coating steel, non-ferrous foundries, metallurgy, spun pipes, tools, and refractories.<\/p>\n

Know the Types of Refractory<\/h2>\n

Various types of refractory can help you decide for an ideal refractory project<\/span><\/p><\/blockquote>\n

Generally, refractories come in all shapes and sizes. Plus, it has a profound resistance against heat-related harm. Besides this, the type of refractory is also wear-resistant <\/strong>and corrosion-resistant.<\/strong><\/p>\n

Therefore<\/span><\/span>, consider the many factors before choosing the right type of refractory. So, <\/span>choose the best refractory contractor<\/a><\/strong> to help you with a durable refractory project.<\/span><\/p>\n
