Oven wall straightener

An oven particularly adapted for heating wire comprising a heat source and oven walls to contain heat generated by the heat source, wherein the improvement comprises at least one oven wall having an oven wall straightener, the oven wall straightener comprising:

• a. an angled beam having two sloping sides and a vertex;
• b. means to secure one end of the angled beam to a portion of an oven wall such that the angled beam extends vertically along the oven wall with the vertex of the beam running in parallel opposition to the oven wall;
• c. a plurality of insulating pads separating the angled beam from the oven wall;
• d. a plurality of beam straps located at spaced intervals along the vertex of the angled beam, each beam strap having a first end, and a second end wherein the first end is attached to the oven wall proximally to one side of the angled beam and the second end is attached to the oven wall proximally to the other side of the angled beam such that the beam strap contacts the angled beam only at the vertex of the angled beam;
• wherein the beam straps can conduct heat to the vertex of the angled beam causing the angled beam to bow outward away from the oven wall thereby preventing the oven wall from bowing inwardly.
