The chemical composition of the molten glass comprises the following constituents, in a content by weight, within the following limits: SiO2, 39-55%; Al2O3, 16-27%; CaO, 3-35%; MgO, 0-5%; Na2O+K2O, 9-17%; Fe2O3, 0-15%; and B2O3, 0-8%. The melting stage is carried out by electric melting in a furnace that has a tank made of refractory blocks and at least two electrodes immersed in the molten glass. At least one of the refractory blocks, in contact with the molten glass, is made of a material having at least 60% by weight of zirconium oxide and less than 5% by weight of chromium oxide.

  • Patent number: 8104311
    Abstract: Tubular pipe insulation is made from a glass fiber mat produced utilizing a rotary glass fiberization process. A spinner disc is rotated to centrifuge molten glass through fiberization holes in an annular sidewall of the spinner disc and form primary glass fibers. The primary glass fibers are attenuated and formed into a veil where the fibers are dispersed to reduce in length the fiber networks formed from the fibers. Binder is applied to the fibers and the fibers are collected into a mat that, when pulled apart by longitudinally directed, opposing forces, separates across the width of the mat into two mat sections having feathered edges with substantially no fibrous stringers extending beyond the feathered edges for a distance greater than about four inches. The leading mat section is then wound about a mandrel and the binder in the mat is cured to form the pipe insulation.

A downward annular flow of attenuating gases is directed to attenuate the streams of molten mineral material into mineral fibers. A mixture of combustion air and combustion gas is supplied to an annular burner positioned around the spinner. Heat from the annular burner is directed toward the spinner and the streams of molten mineral material to heat the spinner and assist in attenuating the streams of molten mineral material into mineral fibers. A pressure sensor senses the pressure of the combustion air prior to the introduction of the combustion air to the burner. The pressure of the combustion air is controlled in response to the sensed pressure to maintain the pressure of the combustion air at a specific pressure.

  • Patent number: 6843075
    Abstract: A method of controlling process variables, for a fiberizing assembly including a rotary fiberizing disk in the manufacture of fibers from a high temperature, molten, clear or translucent, thermoplastic, fiberizable material, utilizes an optical sensor assembly. The optical sensor assembly includes a water-cooled optical fiber sensor probe which, in effect, only gathers light emitted from the external sidewall surface of the rotary fiberizing disk. The light is conducted from the probe to an electronic unit that converts the light energy into a temperature value. This temperature value is used to monitor the process and to make any changes in process variables, such as but not limited to heat input to the fiberizing disk, rate of rotation of the fiberizing disk, burner air/fuel ratio, required to produce fibers having desired fiber properties.

The insulation products can provide the same thermal resistance or R-value with reductions in fiber density of at least about 20% or more while achieving acceptable recovery of the nominal thickness following compression. The methods can produce fine diameter glass fibers with fewer defects through a combination of lower attenuating gas velocities and the use of spinners having more and smaller holes. A preferred method uses a device for internal centrifugation of mineral fibers including a centrifuge equipped with a peripheral bland perforated with orifices distributed in a plurality of annular zones arranged on top of each other, assuming that the centrifuge is in centrifugation position.
