ML Furnaces Limited Heat treatment of metals is necessary to develop mechanical properties for particular end uses. In glass manufacture similar temperatures are used to control the cooling rate to prevent fracture or to allow the glass to flow to form new shapes. M L Furnaces Ltd have developed a range of ovens from small bench top units which may be used for research laboratory development to large capacity units suitable for larger or production operations. This page draws together the title pages for the units which are most likely to be of use as well as including a few which may be of a interest to other parts of your operation. Low temperature applications For relatively low temperature applications ovens can be found in the bench top range which can accommodate items up to about 500mm cube and also offer air circulation as a means of improving uniformity of temperature distribution. Where rapid turn-around is required the Rapid drying ovens are available. These have larger outlet vents and greater power input to allow for the extra heat and air flow required. For large items up to about 1000mm cube or where shelves of smaller items are required there is a range of larger drying ovens as standard units or they can be made to measure as single or multiple chamber units. These units generally have maximum operating temperatures below 250°C and frequently have air circulation to allow the temperature distribution in the working chamber to be less than ± 5°C of the set temperature. Medium temperature applications A more useful temperature range for studios workshops and tool manufacture and refurbishment will be found in the range of air circulating ovens designed for these temperatures. They include small bench furnaces and larger floor standing production units. This range of ovens can also be used to a maximum operating temperature of 650°C to 700°C. High temperature applications Where metals and other materials are used there may be a call for higher temperatures of operation. Heat treatment above about 750°C can generally be satisfactorily achieved without the need for air circulation since radiation begins to play a significant part in temperature distribution. It is also difficult to construct satisfactory bearings and fan blades to operate above this temperature. The M L Furnaces Ltd range for heat treatment furnaces begins with the annealing oven (including tempering and other practices) mentioned above and extends to the M range of furnaces for temperatures up to 1200°C with chamber sizes taking ware fro 50 x 50 x 100mm to about 250 x 250 x 300mm. Other sizes of furnace can be built to order. Within this temperature band is a top loading furnace which can be used with or without a crucible. In the crucible configuration an A6 size crucible can be used for melting copper alloys. It could also be used with care as an aluminum melter. Other furnaces Chamber furnaces with front loading or bottom loading are available to work at temperatures up to 1800°C. Ranges of tube furnaces with different operating temperatures and tube diameters are also available. Bottom Loading furnace Top Loading furnace Tube furnace
