Main reasons for this are modern imports, one high alumina range suits all business and applications, less varieties to stock, higher markup and margin, those are the reasons if 18% to 26% brick isn’t sold by a store. Higher grades won’t create magic temperature difference in cooking environment and vise verse. However one can get used to cooking in such oven fast.Įven though you can hear other words from a few suppliers who sell not locally manufactured product, conductivity and heat absorbing capacity is not influenced much at all by higher or lower alumina content. from under pizza dough bases being cooked or bread dough. Absolutely safely 18% AL amount firebricks can be used in wood ovens (you can melt and cast color metals in it too.) Furnace’s chamber build out of 18% will perform and last the same way as 30% alumina product.Īpart higher co$t, additionally, higher Alumina content grades make these bricks harder and brittle (more glossy if you like) making them absorb less steam e.g.
No need to apply above 26% in wood fired oven temperatures range but you can in case a low grade isn’t available to buy. Alumina influences bulk density a lot and therefore also porosity, or if you like the weight of fire bricks. The percentage range is important for choosing the right product for the right temperature or Orton Cone but mainly if a high temps are applied. When it comes to fire-bricks and dense refractory products composition content often Alumina (AL) ingredient is looked at which ranges ordinarily between 18% to 40% of alumina in modern product’s body.

The cutting diamond wheel will last you for a long time if the firebricks are cut wet plus you won’t breath in any dust, and of course cutting gets a lot easier and faster! What firebricks type to use? Leave the bricks in that water for 5 minutes minimum. Before cutting soak the brick in water by dipping it in a bucket of water or in a wheelbarrow if you had too many. It is fun and quick but may you want to achieve precise nice cuts hire a trade machine or buy yourself at least small size grinder. Fire bricks can be chopped in half easily by using brick chisel and a couple of hits with a heavier hammer. Dense firebricks can be cut only with diamond wheel attached to high speed handheld angle grinders, on an ordinary building brick saw or sliding drop saw for cutting bricks. Some may confuse them with insulating lightweight firebricks, those are used in different applications. Fire clay bricks are very heavy/dense having low porosity and even on various re-heating, and under continuous heat, they will last for very/very long time.
They are used for instance for building cooking chamber in wood fired ovens, for creating fireplaces, all sorts of fire boxes and wood heaters’ lining, linings in a small or the hugest industrial furnaces, you name it. Some shops call these bricks fireplace bricks. Nowadays they are called heavy and dense Firebricks but old masters still call them fire clay bricks just because they are made of simple fireclay (which actually is the most ordinary mud.) Fire clay can be easily located out in the nature but it must containing the right refractory properties, suitable content ratio of silica and alumina.
