Expansion Shell

The Dewaxing Autoclave is used for removing the wax patterns in the ceramic shell in the investment casting line. It is designed as an integration of steam boiler (outer chamber) and de-wax chamber (inner chamber) to save space and easy for maintenance. It is important that the inner chamber is always in the high temperature atmosphere, when the the high-temperature steam in outer chamber enters inner side, the pressure balance time is fast to reduce the moisture content in the drained wax, the time needed to process the recovered wax is short and the damage is less, thus to increase the wax recirculating efficiency and decrease the production cost. Because of the rapid pressure balance time, the out of the ceramic shell will be pressed in a short time to avoid cracking due to the wax heat expansion. Therefore, the ceramic shell can get a good performance by using this Dewaxing Autoclave. This machine has been used widely in many foundries worldwide.

china coal 0001 Arc Plate Net Shell Support Keywords: Net Shell Support, Stainless Steel Support, Steel Supports Price Introduction of Arc Plate Net Shell Support Supporting of soft rock tunnel excavation has been one of the key technical problems which affects the further development of coal industry production and construction of our country . Deep mine ground pressure intensity is high, under the condition of mining influence and impact ground pressure and strata control is especially difficult, thus support system is more and more strengthened, such as the need to reduce the frame from u-shape set, strengthen the link rod, and even to use U36 steel;spray the anchor net supporting to reinforced by steel arch, or and anchor rope combined support, surrounding rock grouting, etc; Although this can achieve certain supporting effect, but support cost is very high. Therefore, China coal group design to create a new type of flat net shell components, the main supporting characteristics of arc plate net shell components summed up as: "while digging, while supported edge, "before soft to hard", enough stiffness, process simple,low price." Characteristics of Arc Plate Net Shell Support 1,"While digging, while supported edge",timely support Arc Plate Net Shell Support can use waste rock filling, grey package after wall, concrete precast slab, such as filling, network frame and the tunnel contour quickly close to stick, while digging, timely support, so that on the one hand can make the support resistance of support was able to play in time, to timely reinforce the surrounding rock and to work under the stress state in three; On the other hand, have the effect of slow pressure, pressure, lead to the uniform support along the perimeter stress, is in good working condition. 2,Arc Plate Net Shell Support has enough "rigidity" 3,"Just moderately soft, before soft to hard". Arc Plate Net Shell Support force has a complex ingredients: expansion and creep of rock mass, reduce the strength of long, crushing of rock mass adhesion coefficient reduced values, etc., all show the macroscopic displacement of rock mass and any rigid support to prevent displacement will be entirely itself in disadvantage. Therefore, the stability of the laneway to end support, work together to complete of the surrounding rock. Reticulated shell scaffold, while under high in-situ stress reaction in surrounding rock, making convergence of surrounding rock in supporting under the control of convergence, by stent supported edge, the edge of broken rock mass convergence pressure unceasingly, forming a stable bearing ring, together with stents to assume the role of in-situ stress. The scalability of Arc Plate Net Shell Support comes from two aspects: (1) the contact of the spatial grid steel supports and surrounding rock itself has certain yielding; (2) the junctions between the reticulated shell scaffold piece and piece of wood plate.
