Dura-Line Furnaces

Dura-Line™ Furnaces are ideal for when you want big furnace features in a midsize melter. They have a body constructed of heavy, cast refractory top and bottom sections with stainless steel reinforcement, providing a strong and rigid support for the heavy-duty, copper power coil and the working lining. The full-section cast metal side plates complete the structure and provide mounting support for the tilting trunnion and hydraulic tilting cylinders. Large diameter vertical and horizontal stainless steel tie rods ensure complete structural integrity. The same construction is used for either hoist or hydraulic tilting furnaces, providing single-trunnion action and “nose-title” pouring. For front exiting leads, a metallic splash plate across the front of the furnace provides full protection to the coil during melting and pouring and is easily removed to connect the water-cooled leads and for maintenance. Hydraulically operated furnaces are provided with stanchions that protect the cylinders and hydraulic piping.

Dura-Line™ Furnaces with an Optional Double-Trunnion, Hydraulic Tilt Design offers the precision pouring control you need if your induction melting and casting operation requires a precise pour into a stationary opening. This design features two separate pivot axes for a smooth and controlled pouring action. As Double-Trunnion, Hydraulic Tilt Dura-Line™ Furnaces are tilted for pouring, the pivot point moves from the first axis, which is closer to the center of the furnace, to the second axis, which is in line with the tip of the pouring spout. This carefully designed tilting mechanism ensures minimum travel of the molten metal stream once pouring has started, while providing maximum “reach”. The Double-Trunnion, Hydraulic Tilt Dura-Line™ Furnace’s smooth and controlled pouring action makes it ideal when an exact pour position must be maintained. This action also permits faster controlled pouring.

Security options are modified to protect your device against possible failures. In order to improve the overall efficiency and safety of each device, Taiwan Yingda offers options that can be modified as needed to give you the most advanced equipment that does not require replacement of the entire unit, including the following:

• The tightly trapped flue gas cap meets the customer’s MACT requirements. We offer a full set of flue gas caps that can be retrofitted to almost all sizes and existing Taiwanese yoke induction furnaces. These flue gas caps are designed to efficiently collect smoke, dust and air pollution during all phases of the melt operation.
• The smelting of the lining system through the use of large removable plugs

The entire lining is pushed out in a few minutes for easy handling, thus reducing the amount

Time and labor for replacing the refractory lining. It reduces the exposure of foundry personnel to refractory dust environments and improves the working environment, making them more productive and profitable.

• The back end slag causes the furnace to tilt back 33 degrees. The tilting furnace provides sufficient space above the mobile funnel platform to facilitate the discharge of slag from the rear slag tap to the funnel.
• The application of the rear end tilting is when the slag is discharged at an angle of about 12 degrees to the rear rake angle, using a lower cost tilting seat with an extended cylinder configuration. Nose tilting rotates the furnace forward, improving the casting accuracy when small casting or controlled casting flow is required.
